Series of magnetic metal-doped cerium oxide (MCeO x , M=Fe, Co and Ni) were synthesized and applied to support nano-gold (Au) as catalyst for synthesis of methyl methacrylate (MMA) through gas-liquid-solid three-phase oxidation esterification of methacrolein (MAL) and methanol (MeOH)....

Rubber composites with high electromagnetic interference (EMI) shielding effectiveness (SE) and excellent thermal insulation properties have potential applications because they can simultaneously resist EMI and display infrared stealth functions. However, the effective integration of shielding...

Consider a nearly nonstationary AR(1) model, Xt=θnXt−1+ut, where θn=1−γ/n, γ is a fixed constant, and the innovations are in the domain of attraction of the normal law with possibly infinite variance. As for the least squares estimator θˆn of θn, we propose to use a residual-based...
